Specification of Letters Patent.

Patented Dec. 28, 1915.

Application tiled March 2S, 1914.-. Serial No. 826,756.

To all "t0/wm 'it may concern Be it known that I, @Niestern E. MICHAUD,a citizen of the United States, and aresident `of the city of St. Louisand State of Missouri, have invented a new and useful Improvement inRoller-Bearings, of which the 4following is a specification.

This invention relates to combined radial and thrust antifrictionbearings similar to the bearings shown in my pending application SerialNo. 791,684, wherein a series of bearing rollers are spacedcircumferentially between inner and outer bearing rings. In the presentinvention the rollers are held in alinement at equal distances apartaround the inner bearing ring by means of spacing rollers arrangedbetween them.

The object of the invention is to provide improved means for maintainingthe bearing rollers in alineinent andfor retaining the bearing rollersand spacing rollers in assembled position around the inner bearn ingring independently of the outer bearing ring.

Other objects of the invention appear in the following description ofthe embodiment of the invention shown in the accompanying drawing.

The invention consists in the parts and [arrangements of partshereinafter described,

ist

parts inclosed therein in elevation.

and is more particularly defined in the appended claims.

. In the drawings, in which the same reference characters are used inthe several views to designate the same or'lile-parts, Figure 1 is aside view of the bearing, showing the outer bearing ring in section andthe Fig. 2 is a part end view and part cross-.section of the bearing,the cross section beingl taken on the line 2 2 in Fig. il, looking inthe direction of the arrows; Fig. 3 is a longitudinal section of thevbearing taken on the line 3 3 in Fig. 2, the bearing rollers beingshown in side elevation; Fig. l is a longitudinal section of the bearingtaken on the line d--d in Fig. 2, the spacing rollers being Y shown inside elevation; and Figs. 5 and 6 ways for the cylindrical end portionsof the are side views of the spacing ring.

As shown in the drawings, the improved device consists of an innerbearing ring 11 having a flange l2 around its periphery intermediate itsends. The outer surface of the inner bearing ring on each sideV of theflange 12 is cylindrical, and forms two race- .bearing rollers 13. 'Thebearing rollers 13 are grooved circumferentially between their endbearing portions, the grooves forming necks lwhich connect the endbearing portions of the bearing rollers. @ne end of each bearing rolleris beveled to form a conigroove adjacent thereto is likewise beveled toform an oppositely disposed conical bearing surface 16. Thetlange 12 onthe inner bearing ring is beveled on one edge to form a conical bearingsurface 17 againstwhich the conical bearing surfaces 16 of the groovedrollers bear. Y Y

Between each two grooved bearing rollers 13 is a cylindrical spacingroller 18 having a straight-sided flange 19 around its middle. Thediameter of the cylindrical ends of the spacing rollers is the same asthat of the cylindrical necks 1d of the bearing rollers. The spacingrollers 18 roll upon the outer edge of the flange 12 on the innerbearing ring. rlhe flange 12 hasA a straight-sided circumferentialgroove 20 forming a track around it into which the flanges 19 fit,thereby retaining the spacing rollers in axial position.

Surrounding the grooved bearing rollers and fianged spacing rollers is aretaining ring 21 which has an internal groove or channel 22 of the samewidth and depth as the groove 20. The retaining ring tits wit-hin thegrooves of the bearing rollers and the flanges 19 of the spacing rollersfit into the channel 22, whereby both the bearing rollers and spacingrollers are retained in assembled position on-the inner bearing ring.

, sprung into and out of engagement. After assembling the inner bearingring, bearing rollers and spacing rollers within the retaining ring sothat it fits in the grooves in the bearing rollers and over the flangesof the spacing rollers, the ends of the retaining ring aresprung-together and thereby fastened. To remove aspacing roller orbearing roller it is only necessary to rotate the retaining ring untilits split portion is over the roller, spring loose the ends of theretaining ring, and spread them apart Sulliciently to slip the rollerbetween them.

The outer bearing ring 25 surrounds the `cal bearing surface 15, `andthe edge of the vthem in said groove.

cylindrical bearing rollers 12, and is provided with an internal flange26 at one end. This flange is beveled on its inner side to form aconical bearing surface 27 against which the conical end bearingsurfaces 15 of the bearing rollers bear. `When all the parts of thebearing ai'e in assembled position, the retaining ring is confinedwithin the grooves in the bearing rollers, and between the bearing andthe spacing i'ollers and the outer bearing ring; and the space betweenthe retaining ring and the outer bearing ring is insufficient to permitthe ends of the retaining i'ing to be sprung loose from each other.Consequently, solong as the outer bearing ring is in place the other`partsfof the bearing cannot be removed, and

the bearing cannot come apart.

VIt is evident from the foregoing description that modifications of theshape and changes in the` arrangement of the parts may be made, and theinvention is not limited to the exact shapes and arrangements shown inthe drawings. v
